filmscanners: Slide scanner question.

["Eric" <biology@ucla.edu>]

hiya there,

 I have a quick question for the group here.

 I am looking for a new slide scanner.. Right now I have a Photosmart
scanner with Vuescan software and it works ok, but with tough slides or dark
slides they don't scan quite that well.

I have been looking at three different scanners.

 Nikon LS IV Coolscan
Nikon Supercoolscan 2000
Polaroid sprint scan 4000

I know someone who has the LS 2000 Scanner and loves it, and I can get one
for around $750.00 new .
I also have heard about the Polaroid scanner and the 200 rebate they are
offering..

Does anyone know about the Nikon LS IV coolscan and a comparison between the
three of them?

I know some of the specs. of all of them, but what is the best one overall?

Thanks

Eric
